FEED-REGU LATO R.

SPECIFICATION forming part of Letters Patent No. 494,984, dated April 4,1893.

Application filed August 22, 1891. Serial No. 403,491. (No model.)

To aaZZ whom it may concern.-

Be it known that I, CHARLES S. EDMONDS, a citizen of the United States,residing at Colleville, in the county of McKean and State ofPennsylvania, have invented certain new and useful Improvements inFeed-Regulators and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertain to make and use thesame.

M y invention relates to automatic feed regulators and especially tothose used in connection with oil stoves, furnaces, and the like.

The invention consists in the peculiar construction of the regulatorwhereby the pressure of steam in the boiler regulates the flow of bothoil and steam to the fire box as hereinafter described and claimed.

The object of the invention is to provide a device that will be botheasy to construct and inexpensive.

In the drawings Figure 1 is a perspective view of my improved automaticfeed regulater; the lower portion being shown in section on the line l-lFig. 3. Fig. 2 is an end elevation of the same; the upper portion beingshown in section. Fig. 3 is a horizontal section of the bases on theline 3-3 Fig. 2.

Referring to the drawings, A represents the bases of the device whichmay be made of any suitable material of convenient form. A, A are pipespassing through said bases and connected to the boiler and oil reservoirrespectively. The standards 0, O, are secured firmly to the bases or maybe cast integral therewith and support the two disks B and B the formerof which is hollowed out forming a chamber 5, the latter being a flatdisk with a circular hole a as shown in Fig. 2. Between these disks isstretched the diaphragm B In the top of disk B is an opening into whichfits the pipe A said pipe being connected to the boiler at one of thewater gages.

Passing up through hole a in disk B and contacting with the under sideof the diaphragm is the piston l3 having the head 3*. This piston isprovided, on its lower end, with the two laterally projecting arms D, Dto which are rigidly secured the valve stems a a which operate thevalves a, a in the steam and oil pipes respectively. These valves arelocated between the bases and at equal distances from the medianlongitudinal center of the piston B Pivoted to one of the standards andcontacting with the lower end of the piston is the arm D upon the leverend of which is suspended an iron counterbalance weight D which may beshifted to give any predetermined amount of steam, said amount beingdetermined from the steam gage.

The operation of the device is as follows: The weight on lever D isadjusted so as to raise the piston B and open valves a and a the head ofthe piston contacting with the diaphragm. Oil and steam pass through thevalves in, and a and steam also enters chamber I) through pipe A andimpinges upon the top of the diaphragm. If the pressure in the boilerincreases sufl'iciently to overcome the weighted lever D, the diaphragmis depressed by the force of steam entering chamberb, the piston forceddownward carrying with it the stems a thus closing valves a and a andcutting ofi the flow of steam and oil through them.

What I claim as new is- 1. An automatic feed regulator comprising thebase, the pipe passed through said base, having a valve provided withavalve-stem, the standards secured to the base, the lower disk having anopening and supported on the standards, the diaphragm located over thelower disk, the upper disk having a chamber and located on the lowerdisk over the diaphragm, the pipe connected with the upper disk, thelever having a counterbalance weight on one arm, and the pistonsupported on the other arm of the lever, having a lateral arm connectedwith the valve-stem and provided with a head occupying the opening inthe lower disk and bearing against the diaphragm, substantially asdescribed.

2. An automatic feed regulator comprising the bases, the pipes passedthrough said bases, having valves provided with valve-stems, thestandards secured to the bases, the lower disk having an opening andsupported on the standards, the diaphragm located over the lower disk,the upper disk havinga chamber and located on the lower disk over thediaphragm, the pipe connected with the upper disk, the lever having acounterbalance weight on one arm, and the piston, supported on the otherarm of the lever, having lateral arms connected with the Valve-stems andprovided with ahead occupying the openingin thelower disk and bearingagainst the diaphragm; substantially as described.
